Facile Synthesis of Isochromanones and Isoquinolones by AuCl3 Catalyzed Cascade Triggered by an Internal Nucleophile
摘要:
Synthesis of isochromanones and isoquinolones comprising a quaternary center with high diastereoselectivity was realized via a AuCl3 catalyzed tandem intramolecular exo-dig heterocyclization/enol isomerization/Claisen rearrangement sequence in excellent yields. The reaction is general and amenable for the synthesis of structurally diverse analogues.
